I just discovered a bug in UML. Under a vanilla edgy eft Ubuntu install as the host (with the linux-generic package installed for the kernel), and using linux2.6.16.29-bs2-32bit (from Blaisorblade) for the guest kernel, using the uml_mconsole HANDLE stop command can freeze the guest permanently. That is to say, i built a backup script which did the following:
1) stop the guest 2) mount the root_fs on the host 3) rsync stuff off of the root_fs (making no changes to the root_fs) 4) unmount the root_fs 5) issue the go command to the guest Some of the time it works just fine. However, out of 20 or so virtual machines, around 5 - 10 of them would freeze and need to be rebooted. They would still respond to pings, but they could neither be screened into, nor ssh, nor any other service would respond. Any ideas? I could install ssh on all the guests, and rsync directly off of them, but that is installing extra services that I'd rather not install and administrate.
